Chapter 35

The United States was now three times as large as it was at Jefferson's election. It contained over three million square miles of land. About one-third of this great area was settled. In the sixty years of the century the population had increased even faster than the area had increased. In 1800 there were five and a half million people living in the United States. In 1860 there were over thirty-one million people within its borders. Of these nearly five millions were white immigrants. More than half of these immigrants had come in the last ten years, and they had practically all of them settled in the free states of the North. Of the whole population of thirty-one millions only twelve millions lived in the slave states, and of these more than four millions were negro slaves.

The control of Congress had now passed into the hands of the free states of the North. The majority of the Representatives had long been from the free states. Now more Senators came from the North than from the South. This was due to the admission of new states. Texas (1845) was the last slave state to be admitted to the Union. Two years later the admission of Wisconsin gave the free states as many votes in the Senate as the slave states had.
